Delayed endothelialization of watchman device identified with cardiac CT

Abstract

These data reveal that the Watchman device remains porous 6 weeks after implantation in a substantial percentage of patients, suggesting delayed endothelialization of the device. Cardiac CT may help to differentiate between peri-device and trans-fabric leak. Additional studies are required to test whether prolonged anticoagulation in patients with trans-fabric leak may help to reduce the risk of DRT and ischemic stroke.
